Goal Attainment Scales (GAS) offer an approach to evaluate changes in the academic and social behaviors of students. The GAS methodology is individualized and criterion-referenced and consists of three steps: 1) selecting a target academic outcome or behavior, 2) describing the target academic outcome or behavior, 3) developing 3-5 descriptions of the target academic outcome or behavior ranging from the least to most favorable. Each description is assigned a numerical rating that allows the scale to be used for ongoing monitoring and reporting of student progress.
